Product attributes are currently recorded as terms in
wp_term_relationships (product attributes are actually taxonomies).
In the case of variable products this is true for the main product,
but not for the variations. The attributes used to define variations
are stored as post meta, but nothing is recorded in the term
relationships table.
This is a problem when using the layered nav filtering plugin,
since the attribute counters displayed are calculated based solely
on the contents of the term relationships table. Adding meta queries
would be really messy (especially when the widget is configured
with AND operator) and would probably also hurt performance.
This commit adds a change to store the attributes for variations
as term relationships, additionally to storing them as post meta.
Terms are stored on variation creation, and updated/deleted together
with the variation as appropriate. "Any" variations (stored in meta
as empty values) are not stored as terms.
Additionally, a database upgrade is included in order to backfill
terms for already existing products.
The layered nav filtering doesn't work well with variable products
when some variations have stock and other don't. When a term is
selected in the widget, a variable product having no stock for
the variation corresponding to that term but having stock for
other variations will be displayed, but it shouldn't.
This commit fixes that by introducing two changes:
- A new override of "is_visible" for WC_Product_Variable that
looks at the supplied filters, compares them against the corresponding
available variations and calculates the visibility based on
the query type (OR or AND).
- A hook on the "found_posts" filter in WC_Query, that adjusts
the posts count based on the found products visibility
when there are filters available; this is needed to sync the
"displaying X posts" messages and the paging when variable
products are hidden due to stock status.
Additionally, the visibility calculated in "found_posts" is cached
as loop variables so that it isn't calculated again when actually
displaying the products.
It is possible for a later duplicate webhook to be fired too early if
the same webhook triggers in one request more than once with the updated
changes from the second one missing if it happens too quickly.
This queues all webhook to be register on shutdown instead of just
syncronous ones to make sure all data from the request is updated first
before the webhook gets queued.
Those methods are a convenient replacement for
"this->factory->user->create". Tests that were using that to
simulate user login have been modified to use the new methods.
When a product is saved its validate_props method is invoked,
and this recalculates the stock_status property based on whether
the product manages stock or not, the stock quantity, and the
value of the woocommerce_notify_no_stock_amount option.
In the case of variable products, and when stock is managed, the stock
was set to "instock" when the current stock was enough, but only
if the "stock_quantity" property was in the list of changed properties
for the object (the method in the base product class doen't check
for changed properties). This is a problem because the
wc_update_product_stock function updates stock_quantity but via direct
database modification, and thus stock_quantity isn't considered
modified. Therefore stock modifications via wc_update_product_stock
don't update stock_status on the product (e.g. when going from 0 to 1
after a refund the stock status will remain as "outofstock").
The fix consists of removing the check for changed properties since
it's not done anyway in the other cases (when stock is below the
woocommerce_notify_no_stock_amount threshold) nor in the base class.
Also, validate_props is refactored for readabiliyy, and an useless
set_stock_status() call placed right before save()
in wc_update_product_stock is removed.
One of the problems with synchronous webhooks is that they are executed as soon as the related action is. Since we may call an action multiple times in the process of updating something, this causes only the first action to trigger the hook. This differs from asynchronous execution because in that case, the web hook will be executed after the entire request has completed.
Right now, when a product having a parent (e.g. a variation having a
parent variable product) is saved, wc_deferred_product_sync is
executed so that product sync is performed at the end of the request.
This commit implements the same when the product is deleted.
- Add methods to temporarily disable and reenable the code hacker.
The code hacker is causing issues in some tests that perform
write operations to the local filesystem. Since this happens only
in a few cases, the easiest fix is to temporarily disable the
code hacker when that happens. This commit adds two new methods
for that in `WC_Unit_Test_Case`: `disable_code_hacker` and
`reenable_code_hacker`.
These methods use a disabling requests count so that the hacker
isn't enabled before it should. E.g. you call `disable`, then
a helper method that does `disable` and `enable`, then `enable` -
then only the last `enable` will have effect.
- `CodeHacker::add_hack` has now a boolean `persistent` parameter.
Persistent hacks won't be cleared by `clear_hacks`.
- `CodeHackerTestHook::executeAfterTest` will now disable the hacker
only if no persistent hacks are registered.
- The existing `file_copy` method is made static for consistency.
- `CodeHacker::restore` method renamed to `disable` for clarity.
- Fix how CodeHackerTestHook::executeBeforeTest parses the test name,
to account for warnings and tests with data sets.
- CodeHackerTestHook now includes a executeAfterTest hook that
disables the code hacker (needed to prevent it from inadvertently
altering further tests). Also, clear_hacks is executed in
executeBeforeTest for the same reason.
- CodeHacker gets restore, clear_hacks and is_enabled methods
to support the changes in CodeHackerTestHook.
- FunctionsMockerHack fixed so that it doesn't modify strings
that are class method definitions.
- Added the WC_Unit_Test_Case::file_copy method, it must be used
instead of the PHP built-in "copy" in tests, otherwise tests
that run with the code hacker active will fail.
This is something to investigate.
Since those Notes were created because of WC Admin and the display is handled by WC Admin, it does not make sense to test them without WC Admin.
In addition, the data store that handles these Notices is not loaded without WC Admin.
